# Barbell Lunge

A unilateral squat variation performed with a barbell on the upper back. The lunge develops single-leg strength, hip stability, and addresses bilateral strength imbalances more effectively than bilateral squat variants.

## Execution

1. Set the barbell on a squat rack just below shoulder height. Step under the bar and position it across the upper traps (high bar) or rear delts (low bar). Grip the bar outside the shoulders and unrack by driving both legs up simultaneously.
2. Step back from the rack and set the feet at hip width. Brace the core.
3. Step forward with one leg, landing heel-first. Bend both knees to lower the torso straight down until the rear knee is just above the floor and the front thigh is approximately parallel to the ground. Keep the torso upright and the front shin as vertical as possible.
4. Drive through the front heel to push back to the starting position. Bring the front foot back in line with the rear foot.
5. Alternate legs each rep, or complete all reps on one side before switching.

## Programming Note

The barbell lunge is typically programmed for 3-4 sets of 8-12 reps per leg. It pairs well with bilateral squats in the same session as an accessory movement. Beginners should master bodyweight lunges and dumbbell lunges before loading a barbell. The walking lunge variant adds a dynamic balance challenge, while the reverse lunge reduces shear stress on the front knee and is preferable for trainees with knee sensitivity.
